Privacy Policy

Product: System Monitor for Windows (Stream Deck plugin) · Provider: GRAMSHIFT (Tokyo, Japan) · Last updated: 2026-09-24

Summary

The plugin does not send any data from your PC to GRAMSHIFT or to anyone else, and it does not store it. It reads a few performance numbers from Windows on your own PC and shows them on your Stream Deck keys. It has no account, no online service, no analytics and no telemetry, and it makes no network requests.

What the plugin reads on your PC

These numbers are read only while a System Monitor key is visible on your Stream Deck, about every 2 seconds. Network speed is read through Windows PowerShell, which is included with Windows. The numbers are kept in memory for up to 60 seconds to draw the graph and are then discarded.

Purchases

The plugin is sold on the Elgato Marketplace. Purchases, payments and licenses are handled by Elgato (Corsair) and its payment provider under Elgato's own terms and privacy policy. GRAMSHIFT never receives card details. If Elgato provides us with sales records (for example the date, country and amount of a sale), we use them only for accounting and tax.

Support requests

If you contact us, we receive what you choose to send (for example your email address, your message and any screenshots). We use it only to answer you. Email to contact@gramshift.com is forwarded by our email forwarding provider (ImprovMX) to a mailbox hosted by Google (Gmail), so those providers process support emails on our behalf.

Our role and legal basis

For the numbers read on your PC, the plugin acts only as a tool on your own computer: GRAMSHIFT does not receive or process them. For sales records and support emails, GRAMSHIFT is the controller. We rely on our legitimate interest in answering requests and on legal obligations (for example tax records). GRAMSHIFT is based in Japan, so this information is processed in Japan and by the providers named above.

Your rights

You can ask us to access, correct or delete personal information we hold about you, or object to its use, by emailing contact@gramshift.com. If you are in the EEA or the UK, you can also complain to your local data protection authority.

Retention and deletion

The plugin keeps no data of its own. Uninstalling it from the Stream Deck app removes the plugin and its log file. Support emails are kept only as long as needed to handle the request and meet legal obligations; you can ask us to delete them. Sales records are kept for up to 7 years for accounting and tax.

Changes

If the plugin ever starts to send or store data, this policy will be updated before that change is released, and the date above will change.
